No, just pointing out there are led 's over 500 lumen, and it's not hard
to find them.

No, put it proves the point leds over 500 lumen are out there and as
standard fixtures like pot lights. This means they are becoming mainstream.

There are several listed at over 500 lumen, do a search on google for
600 lumen leds

Yes in deed...........

I have been waiting for an LED  pot lamp that puts out at least 600 lumens
and is dimmable. Hopefully for use with an X10 module. Either that or I have
to replace the wallswitch with a contact unit that doesn't dim.

The CFLs like to flicker on this and the incandescents are just too high
energy consumption, and heat. It will be a high usage motion detector driven
over my sink and acts as a nightlight for random traffic through a large
room. If the LED units matching this spec were cheaper I would just buy one
and get it over with. So far the specs for price haven't been impressive. It
will improve, no doubt.

Pot lighting seems to be one of the few places LED lamps can be used
effectuively. Low lumen and narow flood area make for a higher lux.

Are you talking about a MR16 package?

No, standard medium Edison base

The light output of these is so pathetic and the better whites are worse.
Heat can be a problem for LEDs in an insulated ceiling fixture as their own
heat burns them out.

I have a number of the down light fixtures running MR16 48LED warm
white. The ceiling is insulated. It was only a matter of pushing the
insulation aside a bit and have had no issues with heat. The light
output is good enough to read under, though I use the same units in
dedicated reading lamps. The ceiling lights are around 12 feet high.
